WebMay 24, 2024 · By careful control over the amount of GdL used, crystals suitable for X-ray diffraction can be grown directly from the gel phase (see below).31 Crystal formation required a minimum concentration of GdL of 6 mg mL−1 at this concentration of 2NapAA, correlating with when the pH decreases below 4. WebMay 31, 2024 · The gel method was tested in a variety of different crystallization configurations, including single and double diffusion techniques. The density of the gel primarily affects the morphology of the synthesized crystals, with denser media favouring the needle-like 2/3 Cd-bpp species and diluted ones the 1/2 Cd-bpp bipyramidal one.
